# FREEBL_USE_PRELINK
#
# Most modern version of Linux support a speed optimization scheme where an
# application called prelink modifies programs and shared libraries to quickly
# load if they fit into an already designed address space. In short, prelink
# scans the list of programs and libraries on your system, assigns them a
# predefined space in the the address space, then provides the fixups to the
# library.
#
# The modification of the shared library is correctly detected by the freebl
# FIPS checksum scheme where we check a signed hash of the library against the
# library itself.
#
# The prelink command itself can reverse the process of modification and output
# the prestine shared library as it was before prelink made it's changes.
# This option tells Freebl could use prelink to output the original copy of
# the shared library before prelink modified it.
#
# FREEBL_PRELINK_COMMAND
#
# This is an optional environment variable which can override the default
# prelink command. It could be used on systems that did something similiar to
# prelink but used a different command and syntax. The only requirement is the
# program must take the library as the last argument, the program must output
# the original library to standard out, and the program does not need to take
# any quoted or imbedded spaces in its arguments (except the path to the
# library itself, which can have imbedded spaces or special characters).
